TENS, or Transcutaneous Electrical Nerve Stimulation, is a non-invasive technique used to reduce pain and discomfort in dentistry. It is a safe and effective way to manage pain during dental procedures, and has been used for decades to treat a variety of conditions. In this article, we will explore the different types of TENS, its uses in dentistry, and the benefits it can provide. TENS is a form of electrical stimulation that is used to reduce pain by stimulating the nerves. It works by sending electrical pulses through electrodes placed on the skin.
These pulses block the transmission of pain signals from the nerves to the brain, providing relief from pain. TENS can be used to treat a variety of conditions, including dental pain, muscle spasms, and post-operative pain.
Classification of TENS
TENS can be classified into two main types: low-frequency and high-frequency. Low-frequency TENS is used for chronic pain relief, while high-frequency TENS is used for acute pain relief. Low-frequency TENS works by stimulating the nerves with low-intensity electrical pulses, while high-frequency TENS works by stimulating the nerves with high-intensity electrical pulses.Types and Techniques
TENS can be used in a variety of ways in dentistry.It can be used to reduce pain during tooth decay preparation in pediatric patients, as well as to control pain caused by the injection of local anesthesia. It can also be used in combination with nitrous oxide and oxygen or diazepam to achieve analgesia during dental treatment. TENS can also be used to reduce TMJ pain in patients with poor bite position. In this case, a special TENS unit with a very specific wavelength is applied to the muscles of the head and neck to help specific muscles reach a point of true physiological rest. This technique has been found to reduce pain intensity by 50 to 75%.In addition to its analgesic effect, TENS can also be used to produce non-analgesic physiological effects and has been found to be beneficial in the treatment of xerostomia.
It has been found to increase the rate of salivary flow in healthy individuals, as well as in xerostomic patients.
